Product Overview

The Cisco 5x20S BPE is a cable interface line card for the Cisco uBR10012 that delivers cable modem termination system (CMTS) functions, such as:

  • Physical-layer RF interface (upstream burst demodulation, downstream modulation, RF frequency allocation)
  • Media Access Control (MAC) processing (modem registration, transmission opportunity scheduling, Layer 2 Quality of Service)
  • On-board packet processing

Featuring a highly integrated and robust RF front end and the industry's most advanced DOCSIS processing engine, the Cisco 5x20S BPE enables high-performance, reliable, and secure bidirectional transmission of IP packets over the cable plant for data, voice, and video services. The card supports 6 MHz National Television Systems Committee (NTSC) channel operation, using standard (STD), Harmonic Related Carrier (HRC), or Incremental Related Carrier (IRC) frequency plans conforming to EIA-S542. The card supports downstream channels in the 88 to 860 MHz range, and upstream channels in the 5 to 42 MHz range. Table 1 describes the product's features and benefits.

Advanced RF Front End

The Cisco 5x20S BPE presents the industry's most advanced RF front-end design, combining the highest level of integration with enhanced RF robustness and performance. The innovative design, which utilizes leading physical-layer chips from multiple vendors, features five downstream modulators, five upconverters, and 20 upstream burst receivers on a single line card and embeds the most advanced RF capabilities, such as direct sampling of the upstream channels and ingress noise cancellation.

Superior Media Access Control

The Cisco 5x20S BPE is the first line card to feature dedicated MAC layer hardware for maximum performance in large-scale deployments. The Cisco 5x20S BPE MAC layer hardware enables scalability to thousands of cable modems, simultaneously providing hardware acceleration for sophisticated security features, such as Baseline Privacy (BPI), or processor intensive functionalities, such as concatenation, fragmentation, and Payload Header Suppression (PHS) necessary to deploy advanced data and voice services.
